I wanted to share my experience with castor oil. One week ago I discovered a large lump on the throat of my dog, the size of a golf ball. Remembering I had found info about castor on your site, I quickly started aggressively applying it to the tumor. I personally have been brewing and drinking essiac tea for years. I keep the left over sludge and started putting that in my dogs food. Remarkably, the tumor is now gone. A little of a week has passed and after applying the castor oil almost 5 times a day. Thank you so much. On a side note, I have been using the oil on my face for beautiful skin, on my strained veins on my legs, which have been disppearing, and my mother in law's dog with tumors also as well as an enlarged liver, has been applying it to her dogs tumors and liver area, after a visit to the vet, the second tests showed the liver had shrunk to normal.

When using castor oil on a dog for a non cancerous tumor, do I need to warm the castor oil, and if so, for how long?

Valerie I saw that you used castor oil successfully on your dog's cyst and you also indicated that it had burst. I purchased castor oil for my Boxer's cyst, which has also burst, and noticed that the castor oil has a warning which states "do not use on open wound." So I am wondering if you used it on your dog when the wound was still open. My Boxer keeps licking the wound and so it never seems to have the chance to heal. I was hoping that the castor oil would heal it quickly, but don't want to use it if using it on the open wound is dangerous.

Thanks VG

Did you get any response on the burst cyst and castor oil? I was putting castor oil on a large cyst / lump on the back of my dog's neck every day for about 2 weeks. All of a sudden it grew larger and got hard as a rock. It now has burst slightly. Any idea on what to do? What happened with your pet?

Update on my dog with cyst on neck that slightly burst after 2-3 weeks of castor oil. The original 3"lump turned into the size of my hand overnight. Slight opening of skin occured but no real expulsion of pus. Brought him to vet and excision of huge neck bulge resulted in massive pus/infection. Dog put on mega antibiotics, etc. Almost 2 weeks has passed and original lump is now gone too.... He has another checkup this week. Incision was kept open and cleaned 2-3 x daily to expell infection and cleaned with water under pressure and expelled as well. He was put on Clavamox, Zeniquin, Benadryl and Cimetidine. He weighs 112# Rhodesian Ridgeback. He is excellent and improved after 1-2 day of mega antibiotics.

I can only assume that the castor oil prompted the cyst to progress that had been lying under his skin for a long time.

Vet was puzzled that she thought he had been bitten by a snake. I assured her that he had NOT......no snakes in my yard. I repeatedly told her it probably was the castor oil........she doubted that is what caused the progress in the abcess.

EC: Thank you for the update, Dee!

This is frustrating. A fluid filled cyst and a fatty solid tumor are not the same thing. A cyst is easily popped and drained with a knife or even a needle, but what about a fatty tumor?
Does the castor oil force a cyst to become so large it ruptures? Therefore would it be BAD for a fatty tumor that will never rupture but continue to stay a mass?

I'm confused also. I don't understand how the castor oil works on malignant tumors. My dog has 4 tumors in her mammary gland. Will the castor oil pack help with that? Thanks!

Replied By Mari (Poulsbo, Wa) on 08/15/2011

Has anyone found the castor oil treatment to be effective on mammary gland tumors?

I was just reading on www.castoroilhome.com,

"Castor oil primarily contains ricinoleic acid, a fatty acid component that is notable for its many healing benefits for the human body. Ricinoleic acid possesses the ability to draw toxins and other poisonous components out of the tissues, thereby restoring the health of parts of your body that have been infected.

Castor oil, a natural plant oil extracted from the castor bean seed, is said to pull out tumors from the body, according to American psychic Edgar Cayce. It is often recommended for the treatment of tumors near the surface.

Aside from reducing or dissolving tumors, castor oil is also regarded as a natural remedy for other swellings in the skin. It can be massaged on bunions, moles, warts, calluses, and cysts. There are also reports that uterine fibroid tumors and ovarian cysts that are benign or non-cancerous may also be addressed by castor oil.

They also said, don't use it on cancerous growths as it may aggravate the condition.

My nine year old poodle-mix has had what seems to be a fatty tumor that is a little larger than an eraser. When she was three years old, this was just a skin tag, but over the years it grew and it became mostly round and white.

After benefiting from so many of the remedies here on this site, I decided to try castor oil on the tumor to see if it would go away. Every night, for three weeks, I rubbed a bit of castor oil on the tumor and nothing seemed to be happening.

At exactly the third week, my dog started licking the tumor a lot for the first time and when I checked her, the tumor had split open and there seemed to be a bit of blood and pus. I panicked since I was afraid that she would get an infection (and with the bad economy, I have no money for either of us to go to a doctor at this point) so I put hydrogen peroxide on it to clean it and wrapped it in a bandage so that she couldn't lick on it.

I kept cleaning it regularly and keeping it wrapped, though the wrapping comes off easily and she starts licking it more.

The problem is that the tumor seems to not be healing. The open spot is there and it doesn't look right and I'm afraid to continue to put castor oil on it when it is like this, so I have been continuing to keep it clean with H2O2. I feel really bad that I put my girl through this when the tumor wasn't really bothering her to begin with.

Right now, the tumor is open on top and looks lumpy inside and there is a dark center (reminds me of the dark center that warts have).

I hope that this doesn't mean that this is a cancerous tumor. I just wanted to post this so that you will know what you might be getting into with the application of castor oil. It definitely does something.

An update on Castor Oil and my 9 year-old poodle mix's abnormal growth:

Three weeks of nightly castor oil made the growth rupture.

I then treated it for two weeks alternately with hydrogen peroxide, alcohol and antibiotic ointment, and kept it covered to prevent licking.

After a month, the once large eraser-sized growth is now a flat, reddish, hardened and dry spot. I'm still not confident that this is a good thing since I would like for it to be completely gone. I think that I will let it rest for a week and then begin the castor oil treatment again.

Thanks for everyone's comments. They really help!

Update on "Tumor" with Castor oil treatment:

I had a veterinarian inspect the flattened, bumpy spot that was left after the castor oil ruptured the large growth, and the vet said that it is/was a WART.

So, apparently, castor oil is very activating to tumors and dissolves them. Now that I think that it's a wart, I think that I will use ACV to clear it up.

Thank you to everyone who posts here. This is the greatest resource on the internet and has helped me and my family very much.

Hello, today I just found a golf ball size tumor on my dogs neck, which isn't opened. I came across the castor oil cure and just wanted to know if it would work on the tumor if the tumor felt like it was connected to something inside his neck? It doesn't feel like a loose tumor. I don't mind taking him to the vet if I have to, not that I dont want to, just have to get extra money. I appreciate your time and answer. Thank you soo much.

I have a 10 yr old pitbull. She was diagnosed with a madt cell tumor on her leg a yr ago. I have put her on a grain free diet. She also has a very enlarged spleen and liver but no cancer there. I just started rubbing castor oil on her liver area, I hope this works but can I rub it on her mast cell tumor? I just want her to feel good. Oh tried chemo and it turned her skin black and she had a very serious side effect so I stopped right away.

Replied By Juan (Brookings Oregon) on 12/04/2015

Is it used oil, and when it opens do I need to take her to a vet, I want to learn more about this.

So my dog has a tumor inside of her rectum, is castor oil okay for dogs to eat? Could this still help her?

Replied By Mama To Many (Tennessee) on 04/29/2016

Castor oil can be used internally, but it is often used for constipation. So it could cause diarrhea. You might consider turmeric for your dog as it is an anti-tumor herb. Also, Essiac Tea.
